What are the best opportunities for java in 2021?

Firstly, Java is widely used for building enterprise-scale web applications. Java is known to be extremely stable and so, many large enterprises have adopted it. If you are looking for a development based job at a large organization, Java is the language that you should learn. It is widely used in Android App Development. So if anyone is willing to find a career in Android App Development, he/she should have an intermediate level of experience in Java.

Some of the different domains where Java is used widely are as follows:

  • Financial services: It is used in server-side applications.
  • Big Data: Hadoop MapReduce framework is written using Java.
  • Banking: To deal with transaction management.
  • Stock market: To write algorithms as to which company they should invest in.
  • Retail: Billing applications that you see in a store/restaurant are completely written in Java.
  • Android: Applications are either written in Java or use Java API.
  • Scientific and Research Community: To deal with huge amount of data

Some Advantages of Java compared to others:-

  • An abundance of open-source libraries
  • Automatic memory allocation and garbage collection
  • Follows the OOP paradigm
  • Has the stack allocation system
  • A high degree of platform independence thanks to the JVM feature
  • Highly secure due to the exclusion of explicit pointer and inclusion of a security manager responsible for defining the access of classes
  • Ideal for distributed computing
  • Offers a galore of APIs for accomplishing different tasks, such as database connection, networking, utilities, and XML parsing
  • Supports multithreading

So concluding above all, Java is the most widely used programming language. It is present everywhere. Whichever domain you work in you would surely come across Java Programming.
